pub enum SignedDuration {
    Positive(Duration),
    Negative(Duration),
}
Expand description

A Duration that can be either negative or positive.

Variants§

§

Positive(Duration)

A duration representing a positive measurement of time.

§

Negative(Duration)

A duration representing a negative measurement of time.

Implementations§

source§

impl SignedDuration

source

pub fn checked_add(self, other: Self) -> Option<Self>

impl PartialEq<SignedDuration> for SignedDuration

source§

fn eq(&self, other: &SignedDuration) -> bool
